DEVICE FOR CUTTING SCREW-THREADS AND SHOULDERS 0N AXLES.

SPECIFICATION forming part of Letters Patent No. 242,165, dated May 31, 1881.

i O Application filed March 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, BARNA T. SrowELL, of Perrysburg, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Tools for Guttin g the Shoulders and Screws on Axles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to theaccompanyin g drawings, which form part of this specification.

My invention relates to an improvement in tools for cutting the shoulders and screws on axles 5 and it consists in forming the tool of two pieces, which are held together by setscrews, and forming in and on the edges of these two parts two cutters, having their teeth turned in opposite directions, for cutting the shoulders on the ends of axles, and two series of screw-dies, for the purpose of cutting the screw-thread into those portions of the axle which have been cut away, as will be more fully described hereinafter.

The object of my invention is to provide a tool which can be used for cutting away the shoulders and cutting the screws upon the ends of axles on both sides of the vehicle alike, and that without the necessity of having to remove any other part of the vehicle than the nut and wheel while the tool is being used.

Figure l is a side elevation of my invention complete. Fig. 2 is a plan view of the same. Fig. 3 is an edge view of one of the parts of the tool, showing the screw dies and cutters.

My tool is composed of the two parts A B, of any desired length, width, and thickness that may be preferred, and which is provided with a handle, 0, at each end for turning the tool around after it has been applied to the end of the axle, and then secured thereto by means of the nut which keeps the wheel in position.

In cutting away the shoulder upon the end of the axle by means of either one of the cutters E, which have their teeth turned in difierent directions, so as to be adapted to use upon different sides of the vehicle, a crank may be applied to the handle for the purpose of enabling the tool to be turned more easily; but where the thread is being out upon that portion of the axle which has just been cut away a crank is never necessary. The two cutters have their teeth turned in opposite directions,

because if but a single cutter were used, or the teeth of both cutters run in the same direction, the tool would operate all right upon one side of the vehicle, but when applied to the other side it would be constantly loosening the nut, which should keep it pressed up against the shoulder that is being cut away.

The two parts of the tool are held together by means of the set-screw G, and the upper and shorter part of the tool is held in position by means of vertical grooves cutin thelonger part, as shown in Fig. 2. By means of the tongue and groove here shown the two parts are always kept in line, and there is no danger of imperfect work beingdone. In the inner edge of the two parts of thetool are cutaseries of screwdies, I, of different sizes, and one-half of these dies have the screw-threads turnedin one direction and the otherhalf in the opposite direction. The two series have their threads turned in op posite directions because a die with the threads running in a single direction only will not cut the screws properly upon opposite sides of the vehicle. Different-sized dies are made so as to be adapted to axles of different sizes, and the threads can be cut to any desired depth or with any degree of rapidity by clamping the two parts of the tools more or less tightly aron nd the axle-by means of the set'screws.

To cut away a shoulder on the outer end of the axle after the wheel has become loose, and thus dispense with the use of washers, it is only necessary to remove the wheel, apply the proper cutter to the screw-threaded part of the axle, and then press the tool tightly against the shoulder by means of the nut which has been used to hold the wheel in position. The rapidity of the cutting will depend to a considerable degree upon the force with which the tool is clamped against the shoulder by means of. the nut, and to make the operation more easy a crank may be applied to the tool, as above described. When the shoulder is to be cut away upon the opposite end of the axle, the other cutter must be employed, or the nut will be constantly working loose instead of holding the tool tightly against the end of the axle with the desired degree of force. After the shoulder has been cut away the tool is removed from the axle, and then the screw-die which most nearly fits the end of the axle is applied to it, and the two parts of the tool are clamped together with any desired degree of force by means of the set-screws. The operator then, by catching hold of both ends of the tool, ean out the thread upon that portion which has been cut; away by the cutter.

The great advantage of my tool consists in thefaet that it is specially adapted for use upon all kinds of light-running vehicles, and needs no skilled labor to operate it. Any one can cut away the shoulders upon the axle, whenever the wheel begins to work loose, without the trouble of sending the vehicle to the shop or taking it apart.

Having thus described my invention, I elain1 A tool for cutting the threads and shoulders on axles, composed of the parts A B U, in combination with the set-screws G, for adjusting them, each part being provided with teeth E, for cutting: away the shoulder of the axle, and 25 the dies l, for cutting the screw-threads, substantially as shown.

In testimony whereof I at'tix my signature in presence of two witnesses.
